IMPROVEMENT IN HARVESTER-FINGER S.

Specification forming part of Letters Patent No. 410.28%,dated October13, 18,63.

vImprovements in the Mode of Constructing Harvesting-Fingers; and I dohereby declare.- that the following is a. full'and exact descriptionthereof, reference being had to the aceompanying drawings, and to theletters of reference thereon.

In the drawings, "Figure l is a plan view of the finger. Fig.2 is anelevation of the same. Fig. 3is a plan view of the steel-plate whichforms't'he cuttin g-edges of the harvester-finger. Fig.4'is' a sectionof the plate through line :0 m, Fig. 3. Fig. 5 is a section through linezz. Fig. 6 is a section through-line y y.

The nature of my invention consists in securing the steel plate to thefinger by casting the metal of which the-finger is made around and intothe plate in such a manner as to secure it firmly and cheaply.

A is the finger; B, the steel plate, provided with an indentation, c, atits front end to re-- ceive a corresponding tongue of the finger.

c is'a countersunk hole about the center of the plate.

a a are bevels at the sides of the plate at its rear end.

b is a curved or straight bevel at the rear end of the plate. 7 Inoperating my invention 'the plate is attached toacore of sand. .They arethen pntinto asuitable mold, and the molten metal is run .in, formingthe finger, and running into the countersink c and over the bevels a andb. Theplates are then tempered after they have been cast. Y

It will thus be seen that by this simple means I amenabled to secure thesteel platesto the fingers of harvesters in an exceedinglycheap,efi'ective, and permanent manner.

Having thus fully described the construction and operation of myinvention, what I claim as new, and desire to secure by'Letters Patent,is

Securing the steel plate B to the finger A by means of the countersunkhole 0, into which the metal forming the finger is east.
